Abstract (en)
A system is described which allows the cyclic rotation of prismatic elements forming variable images on advertising boards. It consists of a system of gears with conical coupling at 90<o>, set into motion by a shaft in several sections driven by a motor reduction gear. The correct positioning of the gears on the rotating axis allows the advertising images to be displayed either with uniform synchronised rotation of the elements or with modulated wave form effect. The rotating prismatic elements are furthermore constituted by a central body divided in sections with connection seats for the sections forming the faces of the prism and bearing the various portions of the images to be displayed. <IMAGE>
